With half the original members dead and a two-hour show based substantially on the band's first new album in 24 years, the Who can be forgiven for not getting the stage up on casters and move it around the floor Wednesday at the HP Pavilion in San Jose, as the Rolling Stones did Monday in Oakland. But by the time the group brought the performance to a close with a still-rousing "Won't Get Fooled Again" and a 20-minute "Tommy" medley encore, the capacity crowd was on its feet yelling for more. Pete Townshend, Roger Daltrey and company responded with "Tea and Theatre," a quiet little etude from the new album.
